DRY MEASURER.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application led December 18, 1907. Serial No. 407,087.

To all whom it may concern:

Be it known that I, JOHN JAMES MAR- SHALL-f, a subject of GreatBritain,residing at No. 64; Conference road, Armley, in the city of Leeds andcounty of York, England, have invented new and useful Improvements inDry Measurers, of which the following is a specification.

This invention relates to measuring quantities of dry goods of apulverulent or granular nature, and other suitable substances, such assugar, tea, cereals, and the like, and filling such measured quantitiesinto bags, or other containers, and has particular reference to improvedapparatus for effecting such measurement and filling, at the same time,in a simple and etlicient manner.

To the end in view apparatus designed according to this inventionembodies a measuring chamber having a sloping base, partially slopingtop, with upright front and back, and the front portion made so as to beremovable for cleaning out, or the like purposes. The top part of themeasuring chamber has a contracted portion, abutting on the sloping topand upright back, which is made hollow, across its length to receive acylindrical or quadrant valve for controlling the inlet to the measuringchamber, which is formed in this contracted part, and above andremovably fixed upon this contraction of the measuring chamber is ahopper, and in connection therewith a controlled feed supply.

As it is necessary to provide for the regulation of the capacity of themeasuring chamber apart from the definite or pre-determined quantity orfactor of measurement the chamber is designed to measure, a coactingslide is disposed within the chamber, and this slide is characterized bya splayed end or base and upstanding portion, which passes through thesloping top of the measuring chamber, and is vertically adjustable toregulate the capacity of the measuring chamber.

The sloping base of the measuring chamber has an outlet, in connectionwith which is journaled, upon the measuring chamber,a valve forcontrolling said outlet, and below this valve and removably fixed uponthe measuring chamber, by its top portion, is a filling device, in theform of a spout or funnel, having sides converging to an outlet,

for directing the measured goods, from the measuring chamber, into a bagor container placed immediately beneath the outlet.

The operative elements are put in and out of actuation by hand or otherpower.

In order that the said invention may be more readily understoodreference should be made to the following description and accompanyingdrawings which illustrate apparatus, constructed according to thisinvention, in which- Figure l is a side elevation, showing a machinehaving the measuring chamber divided into three separate compartments,each of definite capacity. Fig. 2 is a front elevation thereof. Figs. 3and 4 show modifications of the inletvalve, and Figs. 5, 6 and 7 aredetail views for elucidatory purposes.

A is the measuring chamber, characterized as aforesaid, which is mountedupon or secured to pillar or support B, having a table C and sustainedby a base D, adapted for receiving and holding means for the actuationof the apparatus.

Each separate compartment of the measuring chamber is of definitecapacity, which is independently variable to compensate in measuring forthe varying bulk of certain goods which are subject to atmosphericconditions. In the arrangement illustrated by the drawings, the separatecompartments A1, A2, and A3, are adapted to measure approximately l, 2,and I lbs. respectively, and the variations in bulk, and consequentlymeasurement, owing to the causes mentioned, is adjusted by theregulating means.

A4 is the front portion of the measuring chamber A, which is madedetachable and to that end is provided with pins or studs E carried bylugs F. Similar lugs F1 are upon the fixed part of the chamber A havingholes to receive the said pins when the parts are brought together, andto facilitate this meeting and eect the necessary joint, they areprepared with even surfaces.

A5, A6, and A7, are the slides coacting with the separate compartmentsof the measuring chamber A, and disposedwithin the front portion A4thereof. The vertical adjustment of these slides is effected by means ofscrew rods G, pivotally connected at their lower ends to the splayed endor base of the slides, and toward their top ends taking into nuts ormilled disks H in abutments I upon the front portion A4 of the measuringchamber sides of the adjustable slides and allow of I the cutting-offsurface of the valve L, with- -in the casing M, approximates a quadrant,25 Y length is coincident with the ,valve casing,

The valve controlling the inlet' to t-he themeasuring chamber and hopperK is of the type shown in Figs. 1, 2 and 5, or in lieu thereof, of thepattern shown in Figs. 3 and 4C. The valve casing in bothcases isinternally divided to form openings therethrough to register with theopenings of the measuring chamber and the hopper K, which is alsodivided to agree with the openings of the valve.

Referring to Fig. 5, it will be seen that is parallel throughout withits axis, and in L1, oscillating in brackets or bearings L? and has astrengthening piece L3, carried by The right extensible coupling O2joined thereto and a branch N1, pivotally jointed to which is anoperating rod N2, which passes, and is pivwhich is constrained by aspiral spring P3, The opposite trunnion has an arm P upon it connectedto R is the valve for controlling the outlet R1 from the measuringchamber A. vThis valve is surface is parallel throughout with its axis,takes the arc of a circle and the curvature of the outlet R1 iscoincident therewith. The valve R is journaled by trunnions R2 inbrackets R3, attached to the measuring chamber A in which it is capableof being oscillated, and has arms RJl to which are attached the lowerparts of the extensible coupling devices O2 aforesaid, the upper partsof which are joined to the arms N and P. These extensible couplingscomprise rods attached to the arms R4 and tubes to the arms scopinguntil the solid end of the tube comes incontact with the end of the rod,which is pressed down, according lto the downward ing'the outlet valve,when operated through The arms R4 are also joined to uring chamber.These springs arel put in tension when the dutlet valve R is opened, and,are sov held while the operative pressure is on.

.S is the filling device which is in the form of a funnel or spoutremovably attachable to the measuring chamber A by clips S2, studs,screws, or the like fastening means.

S1 is the lillingoutlet which may have its -capacity'further contractedbya suitable device to be inserted therein, when required.

As previously described, by arranging tubes or other appropriateconductors from the feed supply to the divided hopper K the separatecompartments of the measuring chamber A, may be worked independently orcollectively, or to interact, that is, any two or more may be workedtogether while the others remain idle, where the number allows of this,which of course will depend number of its compartments. As illustratedby the drawings a convenient arrangement for a three compartmentmeasuring chamber comprises a central passage T and side `are controlledby suitable valves. i

C1 is a receptacle, for preventing waste of material or goods, which isremovably fitted in the table C, so that it `can be emptied into* thehopper at will. j According to Figs. 3 and 4, the cylindrical inletvalve consists of a cylinder U, divided into hollowed out or open partsU1, to correspond with the divisions of the valvecas ing and measuringchamber. In the position shown in Fig. 3, the valve is open. When thesolid part is turned over the openings the valve is closed.

as follows -Normally the outlet valve is closed, and the inlet valveopen. On initial depression of the treadle, the cylindrical or quadrantinlet valve is first closed, and on opened, by the action of theextensible coupling device O2. The measured goods then fall by gravityfrom the measuring chamber down the spout or funnel, forming the lillingdevice, to the bag or other container. On taking off the pressure, theparts are returned to their normal positions by the reflex action of thesprings, the outlet valve being closed and the inlet valve opened, to

chamber.

I claim- An apparatus of the class described cornprising a measuringchamber which is divided into compartments, vertically adjustable slidesmounted in said measuring chamber, screw rods-connected to the slidesand measuring chamber, the latter having a detachable front and acontracted upper inlet other connections tothe body of the measupon the4capacity of the chamberA and theV The modus operandi may be brieflystatedfurther depression, the outlet valve is allow the material to passto the measuringV portion, a superposed hopper having an os-p branchingpassages Tl and T?, all of which l cillatory inlet controlling Valve,the loWer portion of said chamber constituting an out- A let, anoscillatory valve for controlling said outlet, eXtensible couplingsconnecting the said Valves, resilient means joined to the outlet Valveandthe sides of the measuring chamber, an actuating lever connected tosaid couplings, and a separate ller removably located below said outlet.
